El Ciclon sizing

Something seems odd about the listed stack/reach measurements. The medium El Ciclon is listed with a 16.76" reach, which is 0.2" longer than a large Pivot Mach 5.7 with 24.2" top tube. I know from trying some else's bike here in town that a large 5.7 is way too long for me. Another point of reference: An XL 5 Spot with 24.5" TT is listed with 16.4" reach. What gives?
